This code worked for me:-

• You set the request Method by httpCon.setRequestMethod

  URL url = new URL("http://localhost:8080/greeting");
  HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
  httpCon.setDoOutput(true);
  httpCon.setRequestProperty(
                  "Content-Type", "application/json");
  httpCon.setRequestMethod("DELETE");
  OutputStreamWriter out = new OutputStreamWriter(
                  httpCon.getOutputStream());
  ObjectMapper objectMapper = new ObjectMapper();
  out.write(objectMapper.writeValueAsString(new Greeting("foo")));
  out.close();
  httpCon.connect();
